STEAM-GENERATOR FOR COOKING FEED, 84.0.

SPECIFICATION formingpart of Letters Patent No. 246,767, dated September6, 1881.

Application led J une 6, 1881.

To all whom it may concern Be it known that we, HENRY H. HEIsE and JOHNH. KAUFFMAN,ofOolumbia, in the county of Lancaster and'State ofPennsylvania, have invented a new and useful Improvement inSteam-Generators for Cooking Feed, Ste.; and wedo hereby declare thatthe following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of thisspecification, in which- Figures l and 2 represent vertical sections ofour improved steamer.

Our invention relates to improvements in steam-generators for sweatingtobacco, cooking feed, washing clothes, die.; and it consists in thepeculiar construction and arrangement ot' the parts, as hereinafter morefully set forth.

In the accompanying drawings, a represents the base of our improvedsteamer, which is constructed like an ordinary stove-base, supported bylegs b, and provided with draftopenings c, a dumping and shaking grate,d, and an upwardly-projecting circular iiange, c.

7L represents a cylindrical tire box, surrounded by a waterjacket orboiler, t', close-d at its ends, and made cylindrical at its upper andconical ut its lower end, and held in place ou the base a by means ofits own weight and the circular rim or ange c. An orifice is made in thelower conical end of the boiler for drawing oitl water through anordinary spigot, j, inserted in said orifice.

l l are orifices made in the upper cylindrical part of the boiler i forthe reception of a glass water-gage, m, attached to the boiler at theorifices l l.

on represents a feed-pipe for the purpose ot' supplying water to theboiler, made open at both ends and inserted in an oriiice in the top ot'the boiler. rl'he feed-water pipe m is provided with a small opening, a,on one side, near the top ot' the boiler, to allow steam to enter saidpipe and raise or closea vacuum-valve, o, inserted in the upper endofthe water-feeding pipe.

p represents a screw-threaded orifice in the top of the boiler, intowhich is screwed the steam-pipe g, provided with a safety-valve, r, atits upper end, having a spring, s, bearing on its upper face.

t represents the cylindrical fuel-magazine, of the usual construction,suspended in the center of the lire-pot, and into which the fuel ispoured.

(No model.)

a represents the cover of the magazine, and fu a hole in the magazinefor the escape of gas.

w is the pipe for the escape of smoke and products ot' combustion.

By this construction Ait will be seen that water introduced into theboiler through the feed-water pipe will be rapidly heated, and the steamgenerated will pass out through the steam-pipe, to be applied to thecooking of feed or the washing of clothes orother suitable purposes, thesafety-valve relieving the pressure of steam in the boiler when thepressure is too great, and the vacuum-valve preventing the collapsingofthe boiler when condensation of steam arises on the introduction ofwater into the boiler, thereby producing a partial vacuum, causing theopening ofthe vacuum-valve and the introduction ot' air into theboiler.'

In Fig. 2 we have represented the tire-box h, enlarged at its lower end,with an arched top, fr, for the enlarged part, whereby an enlargedheating-surface and greater boiler capacity are attained over theconstruction shown in Fig. l.

For the purpose of increasing materially the heat radiated by thesteamer for heating atobacco-warehouse and at thesametime sweating7tobacco, we employ a lengthening cylinder, y, provided with aeircularrecess, z, in its base, adapted to receive the rim' or ilange c and holdthe cylinder in place on the base a. The upper end of the cylinder y isprovided with a horizontal flange, a', on which thelower end of theboiler and nre-pot rest, and a vertical rim or iiange, b', by means ofwhich the boiler and tire-pot are held in place.

What we claim as our invention is The combination, with the base a,provided with draft-openings c, a shaking and dumping grate, d, and rimc, ot' the cylinder y, provided with the circular recess z, and ilangesa b', lire-box h, having dellecting-arch a2, magazine t, glasswater-gage m, feed-pipe m', having opening a, vacuum-valve o, arrangedin the feed-pipe, and steam-pipe q, having safety valve r, substantiallyas described, and for the purpose set forth.
